IMPROVEMENT IN SASH-SUPPORTERS.

I, ROBERT B. HUGUMN, of the city, county, and State of New York, have invented certain Improvements in ,Windo\v-Sash Supporters, of which the following is a specification.

Aby means of the lever and spring, to adjust itself to -the space between the plate and edge of the sash, the

object being thepermanent fastening of the surface plate to thecasing, giving to the lever and roller freedom of movement independent of such plate, and enproper adjustment and fastening of the working parts to the plate when male, and greater ease in putting into casing, and eiiciency in holding sash.

Descriptionof Accompanying Drawing.

Figures 1land 2, side elevations of sash-supporters, embodying my invention.

Figures 3 and 4, back and front views ofsame.

Figure lshows the use oftwo rollers, &c., `with lever-spring, Working horizontally.

Figure 6 shows one roller, with lever-spring, working horizontally.

General Description.

movable position, on the back side of plate A, and operated and adjusted by means of a spring.

E and E',.journal-rests on arms of lever D.

F, friction surface in lever D. This friction surface may be on the upper or lower side of the roller, as shown in gs. 1 and 2, and divided in the center, admitting the use of a metal and rubber-surfaced roller, &c.

The pressure of the roller, upon this friction surface is regulated by the stilness of the spring used.

G, projection on lever to hold the spring in place.

H', hole through lever D for securing to plate A.

I, securing-piu.

J, spring. y

K, hard vulcanized rubber-covered roller.

Any desired number ofrollers can be used, though only one friction surface is necessary to hold thesash. Theothersnif used, would actas steadyiug-guides, &c.

One holder is put into Ithe casing on each side of the sash, or only one t-o a sash, as desired and prefcrred. The sash is raised by liftingits weight, and

'held in position left by the counterbalanoingcontact of the roller with the friction surface of the lever, pressed on itI by means of the spring. In closing, the additional weight put upon the sash iscarried to the lever, which, by action of the spring, yields back, causing the sash to come readily down.

Claim.

I claim-'- n The arrangement and combination of the lever? holding plate A, movable lever D having friction surthe purposes herein described.

n face F, roller K, and spring J ,substantially as and for B. B. HUGUNIN.
